I Application filcd'February 10, 1908. Serial No. 415,045.

To all whom it may concern:

- ,Be it known that 1, JOHN R. LONG, a citi- Iren of the United States, residing at Akron,

in the county of Summit and State of Ohio, l

have invented certain new and useful Improvements in Wrenches; and I do declare that the following is a full, clear, and exact description of the invention, which will en able others skilled in the art to which it appertains to make and use the same.

My invention has reference to wrenches, and the invention is an improvement on the wrench patented to me under date of the 17th of April, 1906, and numbered 818,180.

In the accompanying drawings, Figure 1 is a side elevation of the wrench, and Fig. 2 is a cross section on line ro -x, and Fig. 3 is an edge view of the wrench. Fig. 4 is a per-- spective view of the inner jaw members, and Fig. 5 is a perspective view of the yoke by which the jaw members are operatively connected.

In the construction of this wrench as com-- pared with the one on which it is an im: provement several notable differences occur which materially differentiate the same from the former wrench, as will now appear. Thus, in the present construction I have a handlebar B provided with an integral jaw -2 at its outer end, whereas in my former construction the handle bar has no jaw at all, but had both jaws relatively slidable thereon. Theprescnl't bar also has two opposite working edges, 3 and 4, the inner of which is straight with thehandle of said bar, while outer edge Q1 back i is tapered from about the middle of the bar to the outer end thereof and terminating at jaw 2, thus producing a gradual reduction in size or cross section of said bar the entire length of said. taper. The

handle bar B, therefore, carries the outer jaw 2 as a part thereof, and has a straight inner working edge to which the base of said jaw stands squarely at right angles.

The other or inner jaw member, D, has a jaw 6 at its outer end faced parallel to jaw 2 and with a straight inner edge 7 corresponding to straight edge 3 on the main bar and slidably resting or mounted on said edge,

while the outer edge 8 of said member is tapered from the back of its jaw 6 at an angle or degree about twice as great relatively as taper 4 in respect to straight edge 3. This greater taper has several values, but especially enables me to get a long and quick ad justment between. jaws. by a relativel short movement ofsaid memberD onlthe andlcr bar, as is obvious, and also promlotes both definite locking of the partsand easy release after use.

C represents the yoke or sleeve by which the-j aw members or parts B and D are operatively united and utilized. Said yoke or sleeve is formed from tubing out the desired length and swaged to shape, and is adfli .Q to bear closely against the sides of oth members to keep them in working position laterally as well as to serve as a connectin and locking medium for said members, an enlarged or spread at its larger edge or end 10 to adapt it to both enfgage about the larger areas of that part 0 the wrench as well as to serve other purposes to be seen, while smaller edge or end 12 presumably I tains the original size of the tube from which it was cut. A stop pin d on. jaw member I) serves to kee the parts operatively together and guiding lhgs 20 or their equivalent may be used.

New, several peculiar and novel features in this wrench over my former wrench are found, first in the broad and conspicuous difference in the location of the jaws, one of said jaws being on the handle-bar and none on the yoke. This relieves the yoke of the direct strain of a jaw and enables me to make a lighter and better wrench. This also throws all the adjustments inward fiom the outer end of the handle-bar instead of outward beyond the end thereof, as formerly, and which made the smaller member bear the greater strain, preventing such taper being given to the shank of said member D as it now has without weakening it too much for service. Now i can taper to practically a pointy and promote good service Again, there is decided improvement in myresent construction and arrangement of yo e C in several respects com ared with my former yoke, and the first to e noted is the angle which the yoke sustains in respect to the straight surface 3 of the handle-bar and in respect to which jaws 2 and 6 are arranged. l1 ormerly the yoke was square with the straight edge 3, and in order to get a grip or bite to lock upon the handle-bar a forwardly thrown under lip was required which came in advance of the jaw face on the yoke and on which I depended to lock the parts. Now, i accomplish the same result in a better way arranging the yoke at an angle of inclinaplacing the yoke substantially as shown I am member was built upon the handle-bar and the jaws were outside of both. Now the work is done directly on the. straight edge of l throws its outer corner 18 forward on bar B yoke and thegitch of slope on the outer the said shank having the jaw t ereon to its extremity, and a yoke t on in respect to straight'edge 3, w ich and its upper corner 19 rearward on shank Dv relatively as seen in Fig. 1, and it holds this attitude throughout all adjustments. The degree of said inclination is seen by dotted lines, y-y Furthermore, this not only gives an effectual locking position to the yoke, but by throwing the two jaws together as I do herein independently of the yoke and enabled to bring the jaws close together and not make accommodation in the yoke. This enables me to follow the jaws back and forth and to always be sure of a definite locking at any given point and easy unlocking, too, because both the pitch or inclination of the edge of shank contribute to both results. Again, by this construction the jaws and the handle bar are brought much nearer together and there is not the objection to the wrench tilting or turning in the hand as formerly, when the added thickness of the smaller jaw the handle-bar and turning of the wrench inv the hand is positively avoided. This is a valuable difference made possible only by my new construction.

What I claim is:

1. A wrench comprising a handlebar having a jaw at its outer end and a tapered working ortion next to said jaw, an inner jaw slida ly mounted directly ,u' on said bar and having a tapered shank, and a yoke slidable as to both jaws and o eratively locking said parts, the said handle-bar and inner jaw and its shank having smooth contact faces, and a continuous taper from said inner jaw to its extremity.

2. A wrench having a handle-bar with a jaw on its outer end and the outer edge of said bar tapered toward said jaw, a jaw with a reversely taperedshank mounted on said bar and a slidable yoke uniting said parts.

3. A wrench having a handle-bar with a tapering outer end having a jaw integral, therewith, a jaw member slidably mounted on said bar and having a shank of greater taper than said bar extending in the opposite direction to the taper on the bar, and a confining yoke about said parts.

4. A Wrench comprising a handle-bar having a tapered outer portion and a jaw rigid with the outer end thereof, a separate jaw member mounted on said bar and having a shank ta ering to smaller dimensions from in which both the said handle bar and jaw member are slidably mounted.

' 5. A wrench having a handle-bar with a tapered outer edge and straight inner edge, a

jaw member having a tapered shank extending rearward from the face of the jaw thereon,. and a sleeve slidably connecting said parts across their tapered portions and widest next to said jaws.

'6. A wrench comprising a handle-bar with an integral jaw at one end and tapered on its back toward said jaw, an inner jaw mounted on said bar and having a shank tapered oppositely from the taper on said bar, and a yoke uniting said parts having a transverse inclination as to said jaws and bearing its full length on both said tapered surfaces.

7. A wrench having a main bar tapered in its outer portion and a fixed jaw at the extremity of said tapered portion, in combina tion with an inner jaw having a shank widest next to said jaw and tapering therefrom to its end, and a sleeve slidably engaged over said parts and shaped internally to conform to the taper of both parts.

8. In wrenches, a main bar with a jaw at one end and a handle at the other and tapered on its outer edge toward said jaw, a slidable jaw member mounted on the inner edge of said bar and having a shank with greater taper than said main bar and reversely thereto, and a yoke slidably engaged over said parts and deepest in cross section next to said slidable jaw.

9. A wrench comprising a handle-bar with a jaw on its outer end and having a straight inner edge and a tapered outer edge running to said jaw, a jaw member having a straight edge resting on the straight edge of said handle-bar and a tapered outer edge, in combination with a yoke sleeved to slide as to both said parts and decreasing in cross section internally to make a closeengagement on both said jaw member and handle-bar, thereby facilitating locking and unlocking of the parts.

10. A wrench having a handle-bar with a fixed jaw on its outer end and tapered to said yoke engaged about both said parts at an inclination to the faces of said jaws and bearing its full length on the said tapered shank and the outer edge of the handle-bar and having both said shank and bar slidable lengthwise therein- 11. A wrench having a handle-bar with a jaw on its outer end and tapered along its outer edge to said jaw, an inner jaw having a shank tapered on its outer edge from the jaw thereon and constructed to engage said handle-bar and keep it in alinement therewith, and a transversely inclined yoke engaged over said shank and handle-bar.

12. A handle-bar having a fixed jaw at its outer end and. smooth working edges, and an inner jaw member having a shank with a straight smooth edge resting on said bar and a tapered outer edge, a yoke slidably mountseams movement of said shank in said yoke.

13. A wrench having a handle-bar with a straight inner edge and a tapered outer edge 1 and a fixed jaw thereon, a jaw member having a shank with a straight inner edge and an outer edge with a greater taper than said handle-bar, a yoke in which both said parts are separately siidable, and means on the end of said shank to confine the same operativeiy within said yoke.

14.
